Abstract
It is possible to make very concentrated solutions of N-coco-, N-oleyl- or N-tallow-propylenediamine acetate which can be diluted without formation of gels or of lumps in a water/dissolving agent solvent. A simple dilution test is given which allows the suitable compositions to be selected. Use of their diluted solutions, in particular for the lubrication of bottles on conveyor lines.
